Attribute Pair Generator

• Easily generate form fields and object information fields with labels.
• Maintain consistent form structure without lots of html overhead:

Using APG, this...

<% apg = AttributePairGenerator.new(foo) %>
<%= form_tag foo_path(foo.id), method: :put do -%>
  <dl>
    <%= apg.text_field(attr: :title, help: "the title of your foo") %>
    <%= apg.date(attr: :starts_at) %>
    <%= apg.plain_text(attr: :status) %>
  </dl>
<% end %>

generates...

<form accept-charset="UTF-8" action="/foo" method="post">
  <dl>
    <dt>
      <label for"title">title</label>
    </dt>
    <dd>
      <input id="title" name="title" type="text" value="bar">
      <span class="help-inline">the title of your foo</span>
    </dd>
    <dt>
      <label for"starts_at">starts at</label>
    </dt>
    <dd>
      <input class="datepicker" id="starts_at" name="starts_at" type="text" value="2013-10-30 05:00:00 +0000">
      <span class="help-inline"></span>
    </dd>
    <dt>
      <label for"status">status</label>
    </dt>
    <dd>
      approved
      <span class="help-inline"></span>
    </dd>
  </dl>
</form>

Installation

Add this line to your application's Gemfile:

gem 'attribute_pair_generator'

And then execute:

$ bundle

Or install it yourself as:

$ gem install attribute_pair_generator

Common Usage

Call any of the apg methods, and pass in a hash of options, common options include:

• attr: using this option alone, you get the label to be a humanized version of the attr, and the value to be the attr called on the initialized object (if it exists)
• label: override the label
• value: override the value
• help: help text shown after the value
• field_options: pass in options to the content_tag for the main desired element (e.g. tag, input, textarea, checkbox)
• dd_options: pass in options to the content_tag for the dd (value)
• prefix: give a prefix to input elements' names and values
• disabled: disable the input element or link
